On the screen immediately after entering your 1095-A, check the box to indicate the policy was shared by somebody that is not on your tax return. You will then enter 50 percent for the "allocation" numbers.
Sure glad you jumped on this one.....Although when all of this ACA stuff started I was sure that if the application was based on joint income, then the tax filing had to be joint also. Guess I was mistaken, even though the healthcare.gov seems to indicate same.
Filing separately automatically disqualifies the Premium Tax Credit (except for cases of spousal abuse or abandonment).
However, if the Advance credit needs to be fully repaid anyways (such as if their combined income is over 400% of the FPL), filing separately can sometimes reduce the total repayment. That is because if one or both of the SEPARATE incomes are below 400% of the FPL, the repayment is limited (see Table 5).
